Nice. That should be usable in many places where you want to give the player a boost.
I remember SoM has a whole list of numerical error code messages that don't give you any info about what's going wrong. I changed some of them to a description of what was making the issue, but I didn't know what caused most of them. That 'no-texture map piece' error would have been a good one to change to a description of the actual issue.
A thought - it might cut down the vertex count a little if you made the sides like in the attached pic.
It's really cool to see someone else making custom parts. Keep up the good work!
